Evans place was clean and matched the photo's. He was friendly and helpful when we arrived. We could even drop off our backpacks early. We had a good stay and i would recommend this place to pretty much anyone. Only if you want to party at khao san road or are just in town for 2 days you might want to find a spot closer to the main tourist attractions.
I really enjoyed evan's neighborhood, the Thai food place on the corner serves the best Tom Ka Kai I ever had, but.. It's not really close to all the tourist stuff. So you will have to take a tuktuk or metro/bus/watertaxi/sky train to the main attractions. You can walk to the Silom night market though, that's pretty close. For me this wasn't a problem at all because the public transportation is really well organized, cheap, clean and air conditioned.. But it is something to keep in mind :)
In short: recommended, good backpacker place!
